DISPENSING-TANK STRUCTURE.

Application filed March 10, 1928.

action.

Second to provide an improved dispensing tank for explosive fluid with safeguard means to prevent the accidental filling of such a gasoline dispensing tank with kerosene and to prevent the accident-a1 dispensing of gasoline from the tank or the accidental filling and dispensing of an explosive fluid for one that is merely combustible.

Third, to provide such a tank that can be readily adjusted for gasoline or kerosene and control both the filling and the dispensing to avoid accidents.

Fourth, to provide such a tank with an improved valve mechanism from which fluid can only be drawn and discharged into containers used for the particular fluid.

Objects pertaining to details and economies of construction and operation will definitely appear from the description to follow. The invention defined in the claims.

A structure embodying in a preferred form the features of my invention'is clearly illustrated in the accompanying drawing, in

My invention applies particularly to dispensing tank wagons. especially those having compartments for dispensing gasoline, kerosene and the like. The structure illustrated applies to such atank having three compartments, all of which are identical except in the matter of deflecting the delivery pipes so that the delivery faucets can be disposed side by side at the end of the tank which in use is the rear of the truck.

It will be readily understood that very serious consequences may follow from the accidental delivery of gasoline. an explosive fluid, in place of kerosene. which is merely combustible. Many scores of lives are lost each year by the accidents which follow such mistakes in delivery. It is important to avoid such accidents. 1 i

In the dispensing of these products it quite desirable to have different grades of 30th gasoline and kerosene carried in different compartments of the same tank, and it is of the utmost importance to insure that an explosive fluid, gasoline, will not be delivered in place of one that is merely combustible. It is only less important that the merely combustible fluid be not delivered by mistake. The annoyance and waste caused by deliv cry of kerosene for gasoline is obvious.

I have therefore provided a construction of tank with delivery faucets with safety devices that are designed to prevent the suspension of a gasoline container on the faucet unless gasoline is to be delivered, and also provide in connection with that safety rid-- justment, connections and mechanism to a shutter control for the intake or filler opening of the tank compartment and a connection therebetween so that when one is adjusted the other will be correspondingly adjusted, and, consequently, when the dispensing faucet shows that gasoline may be drawn.

the intake or filler shutter to the compartment is adjusted and opened for gasoline and closed to kerosene, and vice versa and is closed and shut off until adjusted to correspond to the set of the safety device.

The parts will be identified by their nu morals of reference which are the same in all views.

1 is a truck tank having three compartments for explosive and combustible fluid such as gasoline or kerosene. The compartments and faucet structure and safety devices for each are the same so only one will be detailed and described.

2 is the flanged filler opening, screw threat ed inside, of the usual construction. 3 is the usual screw threaded cover of the filler opening. 4: is the dispensing faucet having upper suspending hook 25 for a gasoline can and lower hook 27 for a kerosene can. 5 is the pipe connection from the under side of the tank to the dispensing faucet which is provided with angle connections if necessary. 6 is the interlocking shutter means to prevent accidental filling of the wrong fluid and is cooperatively connected to the dispensing faucet safety indicators and looks.

The interlocking shutter means consists of the adjustable screw-threaded apertured shutter disk 61 screw threaded in the flanged opening 2 having a screw stop 63 to prevent the turning of the disk through the opening of the tank. .62 is an elongated opening in the disk 61. The gasoline no tale is flanged. and extends at right angles to the filler pipe and the disk 61 should be adjusted to correspond, see Figs. 10 and 10A. The kerosene nozzle is straight in relation to the filler pipe and the plate 61 should be turned ninety degrees as seen in Figs. 11 and 11A. The wrong nozzle thus cannot be introduced to fill the.

- maintained by the screw 82 in one of theholes 84. These holes are on the same angle as the angle of the delivery pipes on the bottom of the tank. The disk shutter 7 is connected to the locking means for the dispensing" faucet by shaft and gear connections so that when the dispensing faucet is set for gasoline the disk shutter 71 will be set for gasoline.

9 is'a universal joint carried by the hub 8. 10 is a connecting shaft. 11 is a universal joint connecting the upright shaft 10 to the sliding extension shaft 131 of the adjusting gear of the interlocking means. 12 is the pipe flange connection iroin the tank to the pipe T 121. 122 is aplug-inserted at the bot tom connection of the T. 123 a supporting post carried by plug 122.

13 is a beveled gear journals-d on the top of the post 123 and carrying the sliding extension shaft 131. A key 132 is provided for slidably operating in the key-way 111 of the lower extension 112 of the universal joint. 133 is a transverse slot in the gear hub to cooperate with the stop pin 12-1 in the post 123. This controls to a quarter turn which is all the movement required.

14: is the delivery pipe connection to the faucet 4 connected by flange l ll to a flange 142 on the dispensing faucet.

15 is a connecting shaft h ving sliding joint with key 151 for long :idinal adjustmentand connection to the control means. 152 is a flexible shaft connection between the rod 15 and the beveed gear 16 for use when the pipe is bent.

The beveled gear 16 journaled at 17 on cross pin 171 carried by the post 123.

The dispensing faucet mechanism con1- prises, a hand lever 18 shown by dotted lines in l mounted on the squared shank 183 of the valve operat rockshaft 180. 182 is a rocker arm on shaft 180 coacting with a disk lift valve 19 of a well-known type. 191 is the valve seat. 192 the valve stem coact' j with the rocker arm 182 of the operating lever. 193 are projecting lugs on the valve to guide and centrally locate the same. 19-l is a bifurcated projecting valve stem carrying the compression spring 20. 41 is a cap with guicing socket 42 for said valve stem.

21 is a locking pin screw threaded "for adjustment in the extension 195 of the valve stem 1941-. 211 is a reduced portion on the locking pin to engage the slots-1212. 22 is the horizontal locking shaft having a tubular BX- tension 221 slotted at 222 to coact with key 151 on rod 15.

23 is the outer bearing for the rod. 231 is the stuffing box therefor. 24 is a hub therefor pinned to the locking shaft. 241 is a projecting handle for locking the suspending hook 25 out of use. 242 is an arm on said hub 24 projecting at right angles to the arm 241 to lock or block the second suspending hook 27 when it is not to be used.

25 is the hook provided on the faucet for the gasoline can 26 as shown by dotted lines in Fig. 3, the bail 261 being elongated and of a greater length than the bail on the kerosene can. The can tops are provided with guards and must be at the right height to receive the fluid being dispensed.

27 is the hook on the faucet for the bail 28 of the kerosene can 281. 29 is a stop for the hand lever of the valve, holding the valve in open position. 30 are the angular pipe connections in the delivery pipe.

An additional locking means is provided whereby the hose coupling 81 screw threaded on the end of the discharge faucet abuts the lower end of the locking slide 311 slotted at 312 to receive the retaining screw 313. It must be understood here that unless arm 242 is closed tight against hook 27, or arm 241 against hook 25, the faucet cannot be closed because the pin 211 cannot drop into the recess 212 to permit the closing. Thus when the hose is connected it is only possible to deliver through the hose, and consequently no other manipulation is possible, and in this position there is protection from any fluid being introduced into the tank that is not intended to be drawn off. It must also be understood that the hooks 25 and 27 can have nothing hung on them and that there can be no hose on the faucet. Also, the faucet must be opened to change the adjustment to permit the entry of a different fluid than that which the tank last contained.

32 is a filling nozzle for gasoline or the like. 33 is a straight filling nozzle for kerosene or the like.

lVhcn the devices are installed on the tank the pipes on each side of the center pipe have connections 30 at an angle from the outlet on the tank. In each case adjustment of the safety device is necessary; otherwise it would throw the valve disk 7 with opening 71 out of proper alinement with the filler nozzle shown in Figs. 10A and 11A. These openings must be in proper alinement with the filler nozzle to get the material in the tank.

To compensate for either the right or left throw of the pipe 14, as shown on the dotted lines 30 in Figs. 1 and 9. and to aline the filler with opening 71 properly, a series of screw .holes 84 in the hub 8 are provided, see Fig. 8A.

ith the parts thus arranged the tank is ready for filling with the particular fluid for which the discharge faucet 4 is set. My improved structure prevents the use of any other container than that for which the discharge faucet is set. For this I provide bails of different lengths. The bail of the gasoline container is of the greater length which insures the using of the proper hook.

When the hook 27 is locked it is impossible to hook the can with the short bail to the hook 25, the distance from the end of the discharge nozzle to the hook being too great. The longer bail 261 can be hooked in the hook 27 used for the kerosene container but by using this hook the end of the nozzle would be above the splash guard of the container, thereby spilling the contents over the bucket and on the ground, which indicates the wrong product is being withdrawn.

A change in the adjustment can only be made when there is no container on either hook and, also, when no hose connection is made, and upon opening valve 19. If the tank contains any fluid it will be spilled on the ground, which indicates the tank has not been emptied, and that an adjustment for a fluid of a different nature should not be made. Under such conditions wrong adjustment would not be done by accident.

All of these operations tend to act as a means for preventing the operator of the truck from vending a fluid that is of an explosive nature for an ordinary combustible fluid or vice versa. -The very dangerous and often fatal accidents resulting from the delivery of gasoline are avoided. The waste and annoyance of delivering kerosene by mistake are obviated.
